Description

The present invention relates to a method and a program for generating a movement route of a moving body, a management server, and a management system.

In recent years, autonomous control of vehicles such as drones (Drone) and unmanned aerial vehicles (UAV: Unmanned Aerial Vehicle) (hereinafter collectively referred to as "aircraft") and unmanned ground vehicles (UGV: Unmanned Ground Vehicle). Possible mobiles are beginning to be used in industry. Under these circumstances, Patent Document 1 discloses a system in which a flying object sequentially photographs an imaged object at a plurality of waypoints set in advance.

Japanese Unexamined Patent Publication No. 2014-089160

However, the disclosed technique of Patent Document 1 uses GNSS (global navigation satellite system) outdoors for self-position estimation, and creates a movement path of a moving body based on latitude / longitude information, and moves indoors. Similar techniques cannot be used in the body's movement path.

Further, when generating a movement path of a moving body indoors (for example, in a structure such as a building), the moving body is manually controlled by using a technique such as Visual SLAM (Simultaneus Localization and Mapping). It is conceivable that the user acquires the indoor three-dimensional information in advance based on the sensor information of the sensor mounted on the device and the user sets the movement route based on the information. However, the SLAM data is visually recognized by the user. In order to do so, it is difficult to understand the overall structure of the structure, it is difficult to identify the route to be actually moved or the object to be photographed in the structure, and it is difficult to set a precise route sufficient for operation.

Further, there is a desire to create a flight path that straddles the inside and outside of the structure, but as described above, it is difficult to integrate these because the method of creating the flight path is different inside and outside the structure.

The present invention has been made in view of such a background, and provides a movement route generation method, a management server, and the like capable of setting a movement route of an autonomously moving moving body including at least a movement route in a structure. The purpose.

The main invention of the present invention for solving the above-mentioned problems is a movement route generation method for generating a movement path in a structure for a moving body to move, and the three-dimensional reference data generation unit is used in the structure. Based on the 3D model data that shows the arrangement of the components and has the dimensional information, and the 3D map data, the step of generating the 3D reference data in which the 3D model data is arranged in the 3D map data, and the movement.

<Management server function>
FIG. 5 is a block diagram illustrating the functions implemented in the management server 1. In the embodiment of the present invention, a three-dimensional model data showing the arrangement of components (for example, walls, pillars, stairs, equipment, etc.) in a structure (for example, a building such as a building) and having dimensional information, and a tertiary model. Based on the original map data, a 3D reference data in which the 3D model data is arranged in the 3D map data is generated, and in the 3D reference data, the orthogonal coordinate system of the 3D model and the latitude / longitude coordinate system of the map data are used. Based on one of the reference coordinate systems, it has various functional parts to generate a movement path for a moving body.

In the present embodiment, the management server 1 includes a communication unit 110, a three-dimensional reference data generation unit 120, a movement route generation unit 130, a movement execution unit 140, an acquisition information output unit 150, and a storage unit 160. Further, the storage unit 160 includes various databases of the three-dimensional data storage unit 161, the movement route information storage unit 162, and the movement information storage unit 163.

The communication unit 110 communicates with the user terminal 2, the mobile body 4, and the mobile body storage device 5. The communication unit 110 also functions as a reception unit that receives various requests, data, and the like from the user terminal 2.

The three-dimensional reference data generation unit 120 arranges the three-dimensional model data in the three-dimensional map data based on the three-dimensional model data showing the arrangement of the components in the structure and having the dimensional information and the three-dimensional map data. Generate reference data. The three-dimensional model data, the three-dimensional map data, and the three-dimensional reference data are data represented in the three-dimensional coordinate system, respectively, and are stored and managed in the three-dimensional data storage unit 161.

The three-dimensional model data is any three-dimensional model data that shows the arrangement of the components in the structure and has dimensional information created based on the data created by CAD (Computer-Aided Design) design software. Such data may be used, for example, 3D model data reconstructed from BIM (Building Information Modeling) data, CAD data, BIM data, etc., or based on 2D design drawing data. It may be three-dimensional model data obtained by generating a structure having a predetermined height, and generation of three-dimensional model data such as reconstruction is executed by a three-dimensional reference data generation unit 120 or the like. Alternatively, it may be executed outside the management server 1 and acquired inside. The three-dimensional model data can be data represented by a three-dimensional Cartesian coordinate system with an arbitrary set point as the origin (reference point).

The three-dimensional map data is a virtual representation of the ground surface and at least a part of the ground surface in a three-dimensional three-dimensional space, for example, in which known aerial photograph data is arranged on a virtual ground. It may be present, or the topography such as mountains and rivers may be reflected as three-dimensional three-dimensional data. The three-dimensional map data may be data expressed in three-dimensional coordinates in which the horizontal direction is the latitude / longitude coordinates and the vertical direction is the altitude coordinates.

The three-dimensional reference data may be, for example, three-dimensional data obtained by arranging and synthesizing the three-dimensional model data on the three-dimensional map data. In the composition, for example, the two may be aligned on the user terminal 2 based on the user operation, and the three-dimensional data of the two may be combined as an integrated three-dimensional data (three-dimensional reference data) at the determined position. In addition, the contour of the lower surface of the 3D model data of the structure and the contour of the structure displayed and grasped on the 3D map data (for example, can be grasped from a bird's-eye view aerial photograph from the sky, etc., can be grasped by the user. It may be arranged as an integrated three-dimensional data (three-dimensional reference data) by arranging them by using known alignment such as associating the contour of the specified structure with the contour and matching the contour. At this time, it is assumed that the scales of the 3D model data and the 3D map data are different. In that case, the scale information of the 3D model data and the scale information of the 3D map data should be compared and the scales should be adjusted. good. The three-dimensional reference data may be data represented by three-dimensional coordinates as a reference coordinate system which is either one of the above-mentioned Cartesian coordinate system of the three-dimensional model and the above-mentioned latitude / longitude coordinate system of the map data.

In this way, the 3D model data and the 3D map data are combined and expressed by a unified 3D reference coordinate system by synthesizing the 3D model data and the 3D map data expressed by different 3D coordinate systems. The three-dimensional coordinate system of the map data will be matched. As a result, for example, when a waypoint is set based on the three-dimensional reference data displayed on the user terminal 2, even if the movement path straddles the inside and the outside of the structure, a unified three-dimensional structure is used. It is possible to specify a position such as a movement route generation based on a reference coordinate system.

The movement route generation unit 130 sets one or more way points for the three-dimensional reference data displayed on the user terminal 2, for example, by a user's selection operation, and the movement route information is based on the way points by a known method. May be generated, stored in the movement path information storage unit 162, and managed, or a way capable of analyzing three-dimensional reference data and acquiring information on a specific or all components in a structure, for example. A movement route in which points are set may be calculated, and this may be stored and managed in the movement route information storage unit 162 as movement route information.

As the movement route, for example, the position of the moving body storage device 5 may be set as the movement start position and the movement end position, and a movement path passing through each waypoint may be generated, or conversely, the moving body storage device 5 may be generated. The position where the aircraft is carried by the user may be set as the movement start position, the user may collect the aircraft at the movement end position, or the like, or the mobile storage device managed by the management server 1 may be used. A configuration generated as a movement path including the position of the moving body storage device 5 selected as the movement start position or the movement end position based on the information of 5 (for example, position information, storage state information, storage device information, etc.). But it may be.

The movement execution unit 140 includes a coordinate conversion unit 141, and refers to the movement route information storage unit 162 and the movement information storage unit 163 to move the moving body 4 for inspection, security, building progress management, and the like. Run.

Here, the coordinate conversion unit 141 will be described. For example, when the latitude / longitude coordinate system is used as the reference coordinate system, the moving body 4 can estimate its own position by GNSS when flying outside the structure, so that the latitude / longitude coordinate system which is the reference coordinate system is used. It is possible to use the expressed movement route information (including waypoint coordinate information) as it is, but if the movement route includes the inside of the structure (indoor), it is in a non-GNSS environment and it is difficult to use it as it is. Therefore, at least a part (including all) of the movement route information expressed in the latitude / longitude coordinate system by using the coordinate conversion unit 141 can be set to arbitrary coordinates (for example, the coordinates of the movement start point or any arbitrary outside the structure). Direction information and distance information from the coordinates of the point, especially the waypoint coordinates immediately before entering the structure) are calculated sequentially or collectively and converted into a Cartesian coordinate system. That is, for example, direction information and distance information from one waypoint to the other waypoint can be calculated based on the coordinates of two predetermined waypoints, so that the direction information can be obtained from any of the above coordinates on the movement path. By calculating the distance information, even if it is a movement route that straddles the structure from outside the structure, it is autonomous based on the information on which direction and how far the moving body 4 travels to reach the next waypoint. Since movement by control is possible, it is possible to execute movement by autonomous control based on the same movement route information even if the movement route straddles the inside and outside of the structure. On the contrary, the movement route information expressed in the Cartesian coordinate system, the current position information, and the information acquisition position information acquired by the moving body 4 are subjected to latitude and longitude based on arbitrary coordinates as a reference in the Cartesian coordinate system. It is also possible to convert it into information and store it in the mobile information storage unit 163, and for example, it may be used in the acquisition information output unit 150 described later.

The movement information storage unit 163 is a parameter used when a movement route is generated by the movement route generation unit 130, or when the movement of the moving body 4 autonomously controlled on the movement execution unit 140 is executed by the movement execution unit 140. It stores information and information acquired at the time of movement acquired on the movement route. Examples of specific parameters include, for example, moving speed, flight altitude (when moving body 4 is a flying body), overlap rate of captured images, information acquired during movement (for example, image information, video information, etc.), and the like. including.

The acquisition information output unit 150 generates output information for transmission to the user terminal 2 based on the movement acquisition information stored in the movement information storage unit 163. In the present embodiment, for example, the acquired information (still image, moving image, voice, or other information) acquired by the moving body 4 on the moving path, or as illustrated in FIG. 7, is three-dimensional. Display that visualizes model data and movement route information, displays the current position based on the current position information, and a symbol that serves as a link for viewing the acquired information corresponding to the position associated with the position information of the acquired information. Three-dimensional data marked with (for example, three-dimensional model data, three-dimensional reference data, three-dimensional map data, etc.) may be output so as to be viewable. Then, by selecting the link on the user terminal 2, the corresponding acquisition information may be displayed. At this time, when the 3D data related to the BIM data is used as the 3D data, it is possible to have the information for each component that constitutes the 3D data in association with the BIM data. (For example, link generation) becomes possible.

<Example of movement route generation method>
The movement route generation method according to the present embodiment will be described with reference to FIGS. 6-7, including the operation of the management system in the present embodiment. FIG. 6 illustrates a flowchart of the movement route generation method according to the present embodiment. In this flowchart, the configuration for starting an application on the user terminal 2 is shown as an example, but the present invention is not limited to this, and for example, the management server 1 and the mobile storage device 5 include a processor and an input / output device capable of starting the application. It may have a configuration capable of various settings and the like. Note that FIG. 7 is an example of a display screen related to the movement route generation method according to the embodiment of the present invention.

First, the user starts an application including, for example, a movement route generation function on the user terminal 2 (SQ101). This application may be stored in, for example, a user terminal 2, or may be software (so-called SaaS) provided by a management server 1 or another server (not shown) connected via a network. If necessary, a login screen may be displayed, and for example, a login ID or password may be requested.

Next, the user creates a new movement plan (SQ102). For example, by setting a "plan name", "area name", "address", etc., the three-dimensional reference data in the target structure is acquired and displayed on the user terminal 2, and a new movement plan is created. Start creating. The 3D reference data may already be generated in advance and stored in the 3D data storage unit 161. At this timing, the 3D model data and the 3D map data are read, and the 3D reference data is generated and displayed. You may try to do it.

Next, the user generates a movement route for the movement of the moving body 4 (SQ103). For example, as illustrated in FIG. 7, the three-dimensional reference data displayed on the user terminal 2 (in the example, the three-dimensional model data generated from the BIM data is arranged on the three-dimensional map data). One or more waypoints (for example, represented by the latitude / longitude coordinate system on the user terminal 2) are set by the user's selection operation, and a known method (in the example, four waypoints) is set based on the waypoints. The movement route information is generated by connecting the spaces with a straight line).

Next, the user instructs the moving body 4 to start executing the movement (SQ104). For example, with reference to the movement route information storage unit 162 and the movement information storage unit 163, the moving body 4 is moved for the purpose of inspection, security, building progress management, and the like. At this time, based on the current position information expressed in the Cartesian coordinate system used by the moving body 4 for movement, the current position information expressed in the latitude / longitude coordinate system is calculated, and the three-dimensional reference data on the user terminal 2 is calculated. The current position information may be superimposed on the display. In particular, the current position of the moving body 4 may be dynamically displayed on the moving path.

Next, the user instructs the management server 1 to output the acquired information (SQ105). For example, the route information actually moved by the moving body 4 may be superimposed and displayed on the three-dimensional reference data displayed on the user terminal 2. In addition, the acquired information (still image, moving image, voice, and other information) acquired by the moving body 4 on the moving path can be displayed, and the position associated with the position information of the acquired information (especially the way point). Three-dimensional data (for example, three-dimensional model data, three-dimensional reference data, etc.) marked with a symbol or the like as a link for browsing the acquired information corresponding to (position information) may be output so as to be viewable. .. Then, by selecting the link on the user terminal 2, the corresponding acquisition information may be displayed. At this time, when the 3D data related to the BIM data is used as the 3D data, it is possible to have the information for each component that constitutes the 3D data in association with the BIM data. (For example, link generation) becomes possible.

As described above, the present invention can provide a movement route generation method, a management server, and the like that can set a movement route of an autonomously moving moving body including at least a movement route in a structure. In addition, instead of the configuration involving the execution of autonomous movement of the moving body 4 of the SQ104 as described above, it may be configured to simply create an optimum moving route, and based on this, another user may make a radio or the like. It is possible to manually display the movement route as a model for moving the moving body 4 in the structure on the user terminal 2 of another user.

Further, in the above-described embodiment, the acquisition of information in the structure by the moving body 4 is taken as a specific example, but for example, the inspection of the structure may be performed, and the presence or absence of a predetermined event on the inner wall and / or the outer wall of the structure may be checked. It may be equipped with equipment, equipment, etc. used for inspection. More specifically, image pickup devices (visible light cameras, infrared cameras, metal detectors, ultrasonic measuring devices, etc.), keying devices, detection devices (metal detectors), sound collectors, odor measuring devices, gas detection, etc. All the devices necessary for knowing the state of the structure to be inspected having an inner wall such as a device, an air pollution measuring device, and a detecting device (a device for detecting cosmic rays, radiation, electromagnetic waves, etc.) can be adopted.

Further, the embodiment may be, for example, security or monitoring in a structure, or may be provided with devices, devices, or the like used for security or monitoring. More specifically, structures to be guarded / monitored, such as image pickup devices (visible light cameras, infrared cameras, dark vision cameras, metal detectors, ultrasonic measuring instruments, etc.) and sensor devices (motion sensors, infrared sensors, etc.). All the devices necessary for imaging and detecting abnormalities and intruders can be adopted.

The moving body of the present invention can be suitably used as a moving body for photography equipped with a camera or the like, and also in the security field, infrastructure monitoring, surveying, sports venues, factories, warehouses, and other buildings and structures. It can also be used in various industries such as inspection and disaster response.
